PERFORMANCE SPECIFICATION FOR AUTOMOTIVE RF CONNECTOR SYSTEMS

2023-07-10

CURRENT

USCAR17-6

This document contains procedures for testing performance of SMB-style electrical terminals, connectors and components for coaxial cable connection systems intended for road vehicle applications. These are often called FAKRA II designs. This specification does not apply to the Non RF portion of a Hybrid RF connection system. The intent of this specification is to qualify sealed and unsealed RF connectors that operate at frequencies from DC to 6 GHz. The characteristic impedance of the SMB/FAKRA connection system is 50 ohms however this specification does not exclude the use of these RF connectors on non-50 ohm cables or systems. This specification does not apply to single conductor wire or twisted pair connection systems. This specification (along with SAE/USCAR 18) is designed to provide the mechanical and electrical data required to insure that assemblies from various manufacturers will perform reliably in actual conditions.

PERFORMANCE SPECIFICATION FOR AUTOMOTIVE WIRE HARNESS RETAINER CLIPS

2023-03-23

CURRENT

USCAR44-2

This specification describes a method and acceptance criteria for testing automotive wire harness retainer clips. Retainer clips are plastic parts that hold a wire harness or electrical connector in a specific position. Typical plastic retainers work by having a set of “branches” that can be inserted into a hole sized to be easy to install but provide acceptable retention. This specification tests retainer clips for mechanical retention when exposed to the mechanical and environmental stresses typically found in automotive applications over a 15-year service life. This specification has several test options to allow the test to match to the expected service conditions. The variability of applications typically arises from different ambient temperatures near the clip, different proximity to automotive fluids, different exposure to standing water or water spray, and different thicknesses of the holes that the clip is inserted into.

ENGINE OIL PUMP PERFORMANCE AND DURABILITY TEST PROCEDURES

2023-03-23

CURRENT

USCAR46

SAE/USCAR-46 defines test methods and outputs for engine oil pump bench testing. Performance and durability testing are the primary focus of this standard. This is written to specifically address testing of electronically controlled variable displacement pumps but can be adapted to mechanically controlled pumps and other pump technologies as needed. This standard outlines critical inputs and outputs in order to perform the testing and report results, but does not specifically set the acceptance standards or pass/fail criteria. Acceptance criteria must be set by the customer.

DIMENSIONAL AND PERFORMANCE SPECIFICATION FOR AFTER-MARKET GASOLINE ENGINE OIL FILTERS

2021-05-13

CURRENT

USCAR36-1

This specification defines the dimensional and performance requirements for aftermarket spin-on oil filters intended for use on gasoline engines. Filters meeting this specification may also be suitable for use on some diesel applications. Filters meeting these dimensional limits are intended to meet the oil filter fit and package requirements for engine and vehicle designs. Filters meeting the performance requirements are intended to maintain sufficient durability to support typical 10000 mile oil change intervals. Some OEM engines may require special filters for which this specification would not support. Filters that meet or exceed this specification requirements for both dimensional and performance can claim “Conformance to SAE/USCAR - 36 Specifications.” Filters that meet just the performance specifications (ie. may have different thread) can claim “Aligns to SAE/USCAR - 36 Performance Specifications.”
